Supposedly a jewelry company located in Suite 1310 of the Acme

Hoag worked. There was actually no thirteenth floor, nor a Detheridge
& Company anywhere in the building. It was almost certainly a front for
the Sons
of the Bird.

Jonathan Hoag

Well-to-do and fastidious gentleman who, realizing he had no idea what he
did every day, hired Ted
Randall and Cynthia
Craig Randall to follow him. This assignment involved them with the
plotting of the Sons
of the Bird, and in untangling the mess Hoag remembered that he was not an
ordinary human being but an "art critic" on Earth to experience human reality
so as to judge the worthiness of the "artistic endeavor", i.e. Earth.

Partner in the investigation firm Randall & Craig, hired by Jonathan
Hoag to discover his profession. Her soul was stolen by the Sons
of the Bird to force her husband to drop the case; after she recovered and
they learned the truth about Hoag, they fled to a remote island to live a
virtual hermit's existence, never leaving each other's presence.

Edward (Ted) Randall

Partner in Randall & Craig, Cynthia's husband. Although he was
attacked and kidnapped by the Sons
of the Bird, he still helped Jonathan
Hoag learn his true nature.

Creatures originally included in Earth's reality by its creator, but
"painted over". Instead of being eliminated, they remained in the background
fomenting evil. They believed they were created by the embodiment of evil,
which they called The Bird. They were destroyed by Jonathan
Hoag after they kidnapped Ted
and Cynthia Randall and tried to stop Hoag's mission on Earth.

St. George Rest Home

Institution in Dubuque, Iowa, where Jonathan
Hoag claimed to have been treated for total amnesia. Ted
Randall's investigation showed that it never existed.

The Heinlein
Society was founded by Virginia Heinlein on behalf of her husband, science
fiction author Robert Anson Heinlein, to "pay forward" the legacy of Robert A. Heinlein to future generations of "Heinlein's Children."
